The researchers who published the 2024 study noted these connections explicitly: the maleness of all 64 analyzed children, the presence of two pairs of identical twins, the subterranean location with its underworld associations, and the overall ritual context.

The Hero Twin narrative provides a framework within which these specific features of the burial make cultural sense.

What it does not provide is proof.

The Popol Vuh was written down in the sixteenth century, centuries after the main period of use of the chultún at Chichén Itzá.

The K’iche’ Maya tradition it represents is related to but not identical with the traditions of the Terminal Classic and earlier Maya of the northern lowlands.

Drawing a direct line from the Popol Vuh narrative to the specific ritual actions at Chichén Itzá requires assumptions about cultural continuity and geographical unity that archaeologists and epigraphers approach with appropriate caution.
